Sentences with phrase «as skyrmions»

Here we show that tailored electron pulses can swiftly write, erase or switch topologically protected magnetic textures such as skyrmions.»

The magnetic knots» nimble nature suggests that skyrmions storing data in a computer could be shuttled to a sensor that would read off the information as the skyrmions pass by.

Not exact matches

A magnetic structure proposed for the natural oddity known as ball lightning makes an appearance in a newfound variety of a knotlike entity called a skyrmion, a team of scientists reports.

On traditional hard drives, the magnetic regions that store data are about 10 times as large as the smallest skyrmions.

Just as there's more than one way to tie a knot, there are several different types of skyrmions, formed with various shapes of magnetic twists.

As some try to shrink room - temp skyrmions down, others are bringing them up to speed, to make for fast reading and writing of data.

Once skyrmions behave as desired, creating a racetrack memory with them is an obvious next step.

Skyrmions don't move in the same direction as an electric current, but at an angle to it.

This effect will be especially important when one wants to move a skyrmion to a selected position as necessary in a future memory device.

When the scientists switched on a specially designed magnetic field, the spins arranged into a twisting structure of loops, knotting up into a configuration known as a Shankar skyrmion.

The skyrmions, as these tiny whirls are called after the British nuclear physicist Tony Skyrme, follow a complex trajectory and even continue to move after the external excitation is switched off.

Because they're stable, only a few nanometers in size, and need just small electric currents to transport them, skyrmions hold potential as the basis for ultra-compact and energy - efficient information storage and processing devices in the future.

The new results, published in AIP Advances, from AIP Publishing, could also lead to skyrmion - based devices such as microwave nano - oscillators, used in a range of applications including wireless communication, imaging systems, radar and GPS.

«Since there is an insatiable appetite for storing information, for uses such as mobile phones, computers, and particularly online, nano - skyrmions are very interesting as an information carrier,» Åkerman says.

Hall and colleagues created their skyrmion in a state of matter called a Bose - Einstein condensate, composed of atoms cooled to a temperature so low that they all take on the same quantum state and begin acting as if they are one unified entity (SN: 10/13/01, p. 230).

In order to use skyrmions as a storage medium, it must be possible to manufacture the surfaces or interfaces on a sufficiently large scale, they must contain enough of the magnetic material, and the magnetic vortex must also occur at room temperature.

Invented as a model of protons and neutrons, knotlike skyrmions could also help explain ball lightning

Swirling objects known as magnetic vortices and skyrmions can be miniaturized without sacrificing mobility, a KAUST - led international research team has found.

Skyrmions, for example, are a kind of nanomagnet, composed of a spin - correlated ensemble of electrons acting as a topological magnet on certain microscopic surfaces.

Scientists want to find a way to create 1 and 0 by using physics phenomena that don't actually change the atomic structure of the material — for example, making a line of skyrmions that could be read as 1s (skyrmion) and 0s (no skyrmion).
